Introducing the cutting-edge heating core of the Leader Ceramic Bobbin Heating Electric Heater for Furnace. This sophisticated electric heating radiant tube features a U-shaped axially arranged core formed by end-welded resistance wires and ceramic support frames, ensuring optimal heat dissipation with no shielding between the inner core and outer protective sleeve. Designed with precision, the electric radiation tube boasts a rated working temperature of 1000 degrees, utilizing Cr20Ni80 or 0Cr21AI6Nb resistance wire, while its surface working temperature reaches an impressive 1200 degrees. Crafted from high alumina ceramic parts, the robust support frame complements the cold drawn seamless thin-walled heat-resistant steel pipe, made of 1Cr25Ni20Si2 or 1Cr25Ni35Si2. This material excels in high-temperature oxidation resistance, offers superior high-temperature creep strength, and demonstrates resilience against carburizing, ensuring a high safety factor in design and material selection. For elevated performance, the radiation tube with 0Cr27AI7Mo2 resistance wire achieves a rated working temperature of 1200 degrees, with surface temperatures peaking at 1400 degrees and short-term working temperatures reaching 1250 degrees. The steel jade porcelain support frame and Fe Ni CrAI Re alloy pipe sleeve provide exceptional oxidation resistance, allowing for continuous operation at 1300 degrees Celsius in oxidizing atmospheres and short-term resilience at 1360 degrees Celsius. This versatile heater is ideal for high-temperature, low oxygen partial pressure, and SC containing environments.
